Best ResponseYou've already chosen the best response.3m= slope so first write the equation y=mx+b where m is slope and b is yintercept substitute x and y for (9,1) point

Best ResponseYou've already chosen the best response.3remember x =something you would draw vertical line (undefined slope when slope is zero you would draw horizontal line

Best ResponseYou've already chosen the best response.0if the slope is 0 that means that \(y_2 = y_1\) so that \(y_2y_1 = 0\) and that only occurrs on a horizontal line

Best ResponseYou've already chosen the best response.0So i know when its 0 its undefined and undefined is vertical line so i just graph it??

Best ResponseYou've already chosen the best response.3when the slope is zero it wouldn't be undefined

Best ResponseYou've already chosen the best response.3vertical line = undefined slope horizontal line = (slope =0)

Best ResponseYou've already chosen the best response.0ok so how do i graph this question

Best ResponseYou've already chosen the best response.3\[\huge\rm \color{reD}{y} = m\color{red}{x}+b\] replace m with 0 and (x,y) with the point (9, 1) solve for b

Best ResponseYou've already chosen the best response.0\(slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ y_2}}{\color{blue}{ y_1}}}{{\color{red}{ x_2}}{\color{red}{ x_1}}}\implies \cfrac{0}{something}\implies 0\impliedby defined \\ \quad \\ \begin{array}{ccllll} x&y \\\hline\\ 9&1\\ 1000&1\\ +1000&1\\ \pm \infty&1 \end{array}\qquad y=1\impliedby \textit{horizontal line}\)

Best ResponseYou've already chosen the best response.3points ? what do you mean ? srry

Best ResponseYou've already chosen the best response.0i have to graph it and to graph u need at least 2 points

Best ResponseYou've already chosen the best response.3you can write an equation with one point and slope \[\huge\rm \color{reD}{y} = m\color{blue}{x}+b\] \[\huge\rm (\color{blue}{x},\color{reD}{y})=(\color{blue}{9},\color{red}{1})\]

Best ResponseYou've already chosen the best response.3substitute y for 1 and x for 9 m=0 \[\huge\rm \color{reD}{1}=9(\color{blue}{0})+b\] (b is yintercept) solve for b

Best ResponseYou've already chosen the best response.3yes right so now we should plugthem into the original equation of slope intercept form \[\huge\rm y=0x+1\] 0 times x= 0 so you have left with y =1 that's what you should graph

Best ResponseYou've already chosen the best response.3dw:1440721541175:dw this one is pretty simple slope is 0 just draw a horizontal line where y =1

Best ResponseYou've already chosen the best response.3and if the equation is \[\huge\rm y=3x+2\] to graph this equation you should always start with the yintercept yintercept is a point where line intersect yaxis

Best ResponseYou've already chosen the best response.3dw:1440721805900:dw yintercept = 2 so draw a point where y =2

Best ResponseYou've already chosen the best response.3dw:1440722012910:dw \[\rm slope =\frac{ rise }{ run }\] in this equation slope =3/1 \[\huge\rm \frac{ rise }{ run }=\frac{ 3 }{ 1 }\] rise =3 run=1 so i'll go 3 units up from 2 and then one unit to the left side
